Abstract

PURPOSE: To attain high-precision character height adjustment through the adjustment of guard drop number in controlling deflection detection.
CONSTITUTION: An ink flux 6 jetted out from an ink jet head 1 is separated into ink drops 7 with a charging electrode 2. The separated ink drops 7 are charged correspondingly to charging signals. The charged ink drops 8 are deflectd with a deflecting electrode 3 correspondingly to the amount of the charges and printed on a recording paper, whereas noncharged ink drops 9 which are not printed are arrested and recovered by a gutter 5 for reuse.
